Most common problems:

Oil leaks

The FLT LA1 V6 engine is known for oil leaks, particularly from the valve cover gaskets and the oil pan gasket.

Intake manifold gasket failure

The intake manifold gaskets in the 2003 Pontiac Aztek's V6 engine frequently fail, leading to coolant leaks and potential engine overheating.

Crankshaft position sensor issues

This engine model often experiences problems with the crankshaft position sensor, causing erratic engine behavior or stalling.

Timing chain wear

With higher mileage, the timing chain in the LA1 engine can wear out, leading to poor engine performance and potential engine damage if not addressed.

Fuel injector problems

The V6 engine in the Aztek can develop issues with the fuel injectors, leading to misfires, rough idle, and decreased fuel efficiency.

Cooling system leaks

This engine configuration is prone to leaks in the cooling system, particularly from the water pump and the radiator, potentially causing overheating.

Egr valve failure

The Exhaust Gas Recirculation (EGR) valve on this engine can fail, resulting in poor emissions performance and rough engine running.
